Gazlux Gas Boiler Error Codes Error E6 It indicates that the ignition is blocked. The ionization flame sensor, which monitors the ignition, reports a malfunction. This component recognizes the presence of a flame and suspends the working cycle of the Gaslux boiler during limited combustion of the main gas burner or in case of failures in the gas supply. Blocking occurs after three unsuccessful inclusions. To restore the functions, you must press and hold the Reset button.

Gas valve failure – The gas valve is electronically controlled. The check of this part is carried out by determining the value of resistance and voltage. If the readings differ from the nominal parameters, it is necessary to change the valve to a new one. There is no gas flow to the device – A valve is located in the gas distribution device, shutting off the gas supply. Therefore, a malfunction when starting the machine may be due to a blocked tap. Incorrect contact or no pulse from the ionization flame sensor. Faulty control board – When the ignition process is running normally, but the machine suddenly goes out anyway, it can be assumed that the electronics do not detect a flame. Based on this, it is required to conduct its testing.

Gaslux boiler overheating problems. The device is blocked. The overheating thermostat has tripped – The overheating thermostat, as well as the temperature sensor, are mainly located on the outlet pipe of the primary heat exchanger. The main purpose of the thermostat is to ensure the safety of the device from elevated temperatures. A malfunction may occur due to problems in the thermostat, temperature sensor, as well as a malfunction in the main circulation circuit. Temperature sensor problems – The control board receives an incorrect signal or a contact failure between the electronic board and the sensor.
Failure of the overheating thermostat – When it is operational, although there has been an actual overheating of the coolant, then there may be a problem with the circulation of the coolant in the heating circuit. There is a blockage in the primary heat exchanger or the main circuit filter element (weak circulation suggests an increased liquid heating temperature). The circulation pump is out of order or there is an air lock in the heating system.

It is a sign of low pressure in the system. The main factors in the appearance of this malfunction: a decrease in water pressure in the heating system. There is no contact between the electronic board and the relay-sensor. The pressure switch has failed. First you need to check the readings of the manometer. Most often, the problem can be eliminated by using a feed valve, which is mounted to supplement the system with coolant. If the problem recurs, it is most likely a water leak. The circulation pump, main heat exchanger, excess pressure relief valve, worn gaskets, make-up tap and other parts can leak. Leakage can be detected by inspecting hydraulic components.
Gazlux Boiler Error Code E1 / E9
There is no traction. In order to ensure the correct and stable operation of the Gazlux gas boiler, draft must be provided to remove combustion products so that they do not enter the room. The outlet of gases is controlled by automatics, and in case of certain problems, the draft sensor will turn on, and the boiler will stop working. Probable reasons for the lack of draft: small size of the discharge channel, improper installation, pollution, icing of the inner wall. Reducing the diameter of the discharge channel entails a lack of traction.
The maximum length of the chimney pipe has been exceeded. We advise you to carefully study the instructions for using the gas boiler and follow the relevant requirements. A sufficiently long horizontal section of the flue pipe can lead to a loss of the necessary draft. Malfunction of the pressure switch-draft sensor – When a vacuum occurs in the supply pipe, a slight click will be noticeable. There is no contact between the control board and the draft sensor, the presence of condensate, as well as poor connection of the tubes to the pneumatic relay. Fan defective – The fan impeller is clogged. The fan shaft is not lubricated, which is why it does not increase the required speed. Lost contact between the electronic board and the fan.
Gazlux Boiler Error Code E3
The hot water temperature sensor is not functioning properly. This code means that the DHW temperature sensor is damaged or the recommended temperature is too high. Probable sources of this problem: the temperature sensor for hot water supply is out of order. Lack of contact between the electronic board and the DHW temperature sensor. Electronic board defective. If the hot water temperature sensor is operational and securely connected to the electronic board, although the device displays an error, then, apparently, the electronic board is faulty.
Gazlux Boiler Error Code E5
Ignition related problems. This situation occurs when there is no ignition or the burner flame is attenuated. It is recommended to diagnose the contacts between the ignition unit and the flame sensor, and also between the gas valve and the board. The main cause of burner flame separation may be weak draft.
Gazlux Boiler Error Code E2
The temperature sensor on the heating circuit is not working correctly. This code indicates that the temperature sensor in the heating system is faulty or the required temperature has increased greatly. An open in the temperature sensor circuit in the heating circuit – This problem most often occurs when the connection between the temperature sensor and the electronic board is interrupted, or the temperature is below the nominal value. After five seconds have passed following the detection of the malfunction, the Gaslux boiler should resume trouble-free operation, in case the malfunction occurred spontaneously.
It should be checked that there is no moisture on the temperature sensor connector and the electronic board connector. If there is no moisture, the temperature sensor must be replaced. A short circuit of the heating water temperature sensor has occurred – This failure may occur when there is a short circuit in the temperature sensor circuit or the temperature of the coolant is above normal. First, it is recommended to measure the resistance of the temperature sensor. If the resistance characteristics differ from the standard, the temperature sensor should be replaced. When replacing the temperature sensor does not help, replace the control board.
